may consume more power as energy is needed to fuel the processors for operation. The
options are Performance, Balanced Performance, Balanced Power, and Power. (Please
note that the options of "Extreme Performance" and "Max Power Efficient" will be supported
when supported by the motherboard.)
CPU P State Control
This feature allows you to configure the following CPU power settings:
AVX P1 (Available when "SpeedStep (P-States)" is set to Enable)
Use this feature to set the appropriate TDP level for the system. The Intel Advanced Vector Extensions (Intel AVX) P1
feature allows you to set the base P1 ratio for Streaming SIMD Extensions (SSE) and AVX workloads. Each P1 ratio has
the corresponding AVX Impressed Current Cathodic Protection (ICCP) pre-grant license level, which refers to the selec-
tion between different AVX ICCP transition levels. Select Normal for the Intel® AVX feature to operate normally, which will
provide a set of instructions to allow Single-Instruction Multiple-Data (SIMD) operations to be performed in Intel processors
by adding MMX and SSE support. The options are Nominal, Level 1, and Level 2.
SpeedStep (P-States)
Enhanced Intel SpeedStep Technology (EIST) allows the system to automatically adjust processor voltage and core
frequency in an effort to reduce power consumption and heat dissipation. Please refer to Intel's website for detailed
information. The options are Disable and Enable.
EIST PSD Function (Available when "SpeedStep (P-States)" is set to Enable)
This feature reduces the latency that occurs when one P-state changes to another, thus allowing the transitions to oc-
cur more frequently. This will allow for more demand-based P-state switching to occur based on the real-time energy
needs of applications so that the power-to-performance balance can be optimized for energy efficiency. The options are
HW_ALL and SW_ALL.
Turbo Mode (Available when "SpeedStep (P-States)" is set to Enable)
Select Enable to allow the CPU to operate at the manufacturer-defined turbo speed by increasing CPU clock frequency.
This feature is available when it is supported by the processors used in the system. The options are Disable and Enable.
Hardware PM State Control

Hardware P-States
If this feature is set to Disable, system hardware will choose a P-state setting for the system based on an OS request.
If this feature is set to Native Mode, hardware will choose a P-state setting based on the OS guidance. If this feature is
set to Native Mode with No Legacy Support, system hardware will choose a P-state setting independently without OS
guidance. The options are Disable, Native Mode, Out of Band Mode, and Native Mode with No Legacy Support.
Frequency Prioritization (Available when the previous item - "Hardware
P-States" is set to "Native Mode with Legacy Support" or using the
Native Mode with No Legacy support)
SST-CP
With Intel Speed Select Technology (Intel SST-CP), surplus frequency is allocated based on the cores' weights. The
weight for each core is assigned by the OS or the Virtual Machine Manager (VMM). The options are Enable and Disable.
